Abstract: Some embodiments relate to a mobile power system. The system includes a first battery module including a number of rechargeable cells. A first battery module current limiter is configured to monitor a current flowing to or from the plurality of rechargeable cells of the first battery module. The battery module current limiter is further configured to selectively limit the current flowing to a non-zero current that is less than a predetermined current threshold, wherein the selectively limiting is based on whether the monitored current is approaching the predetermined current threshold.

Abstract: A motion detector system includes the ability to detect motion through the use of a Doppler radar sensor or a combination of PIR sensors and a Doppler radar sensor. The system includes an outdoor light fixture having one or more lamps and a housing coupled to the outdoor light fixture. The housing includes a Doppler radar sensor and a microprocessor for analyzing the signals received by the Doppler radar sensor. Alternatively, the housing includes a combination of PIR sensors and a Doppler radar sensor and a microprocessor for analyzing the signals received from these sensors. The lamps in the light fixture are activated when either the PIR sensor or the Doppler radar sensor generates a signal indicating motion within the monitored area. Alternatively, the lamps can be activated when either the PIR sensor or the Doppler radar sensor senses predetermined number of motion activities over a limited time period.
